YARN-TUBE.

SPECIFIGATION forming part of Letters Patent No. 534,960, dated February 26, 1895.

' Application filed December 30, 1893. Serial No. 495,174. (No model.)

To all whom it may concern:

Be it known that we, FREDERICK C. KEN- NEDY, residing at Burlington, in the county of Ohittenden and State of Vermont, and HENRY A. VVILBUR, residing at West Somerville, in the county of Middlesex and State of Massachusetts, citizens of the United States, have invented certain new and useful Improvements in Yarn-Tubes; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

Our invention relates to an improved yarn tube; and it consists in the novel manner of constructing the same hereinafter fully described, and further in so constructing the exterior of the tube as to prevent the yarn from slipping.

The object of our invention is to provide a winding tube of superior strength and durability which will hold yarn properly positioned Whether during transportation or while be ing manufactured into textile fabrics, and these ends are attained byconstructingavery substantial tube and by indenting or serrating a strip or edge on its exterior for engagement with the yarn.

Referring to the accompanying drawings, Figure l is a perspective view of our improved tube. Fig. 2 is aview of the blank from which the same is formed.

A designates a blank of paper, sheet metal or any substantial fibrous material, which is formed with a notched or serrated edge 13. The blank is preferably of sufficient size to form a completed tube 0 of four or more laps Which may be secured together with an adhesive or in any other suitable manner. By forming a tube in this way with a plurality of laps a maximum amount of strength and firmness is secured.

The tube isso rolled or formed as to bring its serrated edge B upon the exterior as shown,

and by this means a securing strip is provided which extends the Whole length of the tube, so that as yarn is wound thereon over the serrations it will attain a secure hold on the tube and thus prevent any possibility of slipping, an objection commonly met with in yarn tubes and especially in those of conical FREDERICK G. KENNEDY. HENRY A. WILBUR.
